We have enabled the Amazon SNS notifications from Autoscaling, and 
subscribed a SQS queue to the SNS topic. We have a written a small daemon, 
which runs on the puppet master and consumes from that queue, and calls 
"puppet cert clean" when it receives messages about instances being 
terminated by autoscaling.

We also have it listen for instance launch messages and add their certnames 
into /etc/puppet/autosign.conf and call "puppet cert sign" on them, which 
is also useful for security (you don't have to turn on auto signing for 
everything that way).
